Walk-ons are only on Sundays. You may be able to call and arrange to be included in a group on another day, but that is mainly up to the group and Buddy. you might be limited to using the same equipment as them, however.
As for letting you know when more than 30 will show up on a walk-on day.. as soon as I know that, I would let you know. Best bet is to get on the mailing list if you aren't already, and then check these forums. Call Buddy by Thursday, sometimes he knows a good estimate of how many will be there.
